In this workshop, you'll be introduced to serverless architecture design for building APIs, storing data, and real-time event-based messaging. We'll then dive into building a native Swift iOS app (or two) and cloud-enabling [...]

In this brief, fast-moving, hands-on workshop we'll look at the newest features added to Swift. Although we focus on Swift 5, we also spend some time on other additions from this past year [...]

Course Description The SwiftUI and Combine frameworks will completely alter the way you write iOS, watchOS, and macOS apps. Join Daniel Steinberg for two jam packed, hands-on days which will introduce you to [...]

In this workshop you'll learn everything you need to build a simple Vapor application. You'll learn how to create routes, saves models to a database and build REST APIs. This workshop is fully [...]

Speedrunning a video game is trying to beat the game as quickly as possible. In WWDC terms, this means your intrepid presenter will be shoving as much of WWDC into their face as [...]

SwiftUI makes it easy to create beautiful UIs in no time, but it is just as easy to end up with a giant view that mixes view code and business logic. Fortunately, Apple [...]

SwiftUI comes with some amazing built-in property wrappers like @StateObject, @ObservedObject, @FetchRequest, @Environment and more. But what if you want to add some of your own functionality to SwiftUI? Like maybe a custom [...]

Many companies are coming to realize the many benefits that design systems bring. A good design system (and its accompanying set of engineered components) can improve design quality and consistency and provide significant [...]

Swift 5.7 introduced many changes, including many affecting how we write generics today. In this talk, you’ll be learning how to use opaque & existential types and how they relate to generics.

In the old days, embedded devices were programmed in C++. In this talk I'm going to present a way to interface sensors to the Arduino platform using Swift for Arduino, then collect the [...]

In this session you'll learn about one of the biggest buzz words in Software Development, and one of the most awaited (pun intended) features of the Swift world - async/await, also known as [...]

Managing state and side effects is challenging. Are there some ways out there that can allow us to do that while maintaining separation of concerns and testability?

While Swift Concurrency is amazing, starting to incorporate it into your existing codebase may be slightly intimidating. Let’s talk about that and let’s share our experience with refactoring a Combine SwiftUI app using [...]

"Advanced NSOperations" was one of the most popular WWDC 2015 talks and is still often referred to as a go-to for Swift developers. Nowadays, asynchronous programming is often done with frameworks like Apple's [...]

In this workshop we're going to build Lamstagram - an app just like Instagram but for Llamas - in pure SwiftUI. You don't need any SwiftUI knowledge to attend this workshop. We'll start [...]

When you write unit tests for your projects, there’s a fair chance that you do so by following the classical « Given-When-Then » paradigm, in which you set some input data, execute the [...]

The majority of engineers either debug using print()/NSLog, or utilize debugger for `po` command and ordinary breakpoints, However, Xcode and its debug tools give way more power, starting from powerful LLDB command language [...]

Code generation has always been something of a controversial topic, with many engineers not liking the idea of a codebase that relies too much on this topic. Yet, when used appropriately, this tool [...]
